primer

[bird]

What the heck here is my pennies worth. I primed all parts where they mate. example: where the skin rivets onto the ribs i primed the rib flange and the skin. My thinking is that there is where most corrosion begins, holes are drilled and there is no alcad protection on those edges of the holes. I did this throughout the entire build. We do, as a group, take good care of our airplanes. I think my airplane will be fine after I am long gone. The lifespan, to me, is as long as a person wants it to be, by taking care of it.

This is only stating what I have done. I am happy. So now, I hope you do what will make you happy too!!

Thanks for all the comments. The person who I bought this kit from did not primer the tail section, the fiberglass top is not on yet. I will primer everything I can. the tail section is not going to be much fun now but will do my best. Has anyone used the zinc chromate out of a spray can. I know a lot of airplane machanics in Alaska use this stuff. I guys they just scotchbrite and then spray it on. Anyone out there have any experience with this stuff.

My apologies, Bob; I missed your post. I'll try to be more careful with my wording next time.

For what it's worth, imho, the paint won't stick adequately if you just scuff and shoot.
I scuffed; de-greased (dish soap); mild etch (vinegar, as recommended by paint shop); warm water rinse (water should sheet, no drops); self-etching primer (I used automotive SEM); then rattle can chromate (which I only used at overlaps). I tried skipping steps, and the paint came off.

mmmmmmm, I guess it's not possible. I guess nobody's considered it.............

Presumably you are referring solely to the small percentage of individuals who actually build an entire aircraft from scratch and get it flying. If that is the case then I agree with you.

However it has been estimated that only 20 to 30% of RV builders who start with the empennage ever complete the aircraft. At the moment there are roughly 500 incomplete projects a year coming up for sale on VansAirforce alone. Clearly, many builders are big on dreams and ambition.... but small on persistence.

As for spraying CorrosionX inside your aircraft. Well, it's a second rate solution for protecting an aircraft that was not properly primed in the first place. As others have noted it seeps out of faying surfaces forever making future painting very problematic. It also collects dust and dirt inside the airframe.
